Are Single Embryo Transfers Effective in Young Women?

Posted by New Hope Fertility Center

Traditionally, in vitro fertilization transferred multiple embryos in an attempt to improve success rates.  The theory was that the more embryos transferred, the more likely that one embryo would implant, resulting in pregnancy.  Research and improvements in fertility medicine have shown this is not the case.

Why Would I Elect for Single Embryo Transfers

Posted by NHFC

When faced with fertility care, specifically IVF, many patients believe the best way to become pregnant is by transferring multiple embryos.  Despite this widely held belief, transferring more than one embryo increases the chances of having multiple births, which can result in health issues for both the mother and babies.

New Hope Fertility Center has a unique approach to fertility care.   We encourage our patients to transfer a single embryo during a cycle.   While this technique is relatively new in the United States, numerous studies have shown that single embryo transfer, or SET, is the best way to achieve positive outcomes.   After all, it only takes one embryo to become pregnant.


In April 2013, a clinical study that tracked 175 patients found that pregnancy rates with SET matched that of double embryo transfers.  Rather than transferring multiple embryos, researchers transferred one embryo after screening so that the healthiest embryo was implanted.  Not only were similar pregnancy rates achieved, but better results were received for both the mother and child.  Participants that had SET saw decreases in:

  • Deliveries before reaching full termsingle embryo transfers

  • Multiple birth

  • Babies born with low birth weights

  • The number of days of NICU support

The study found that the frequency of multiple births was significantly different between the group that had multiple embryos transferred and the group that had one embryo transferred.  All of the SET pregnancies resulted in singleton births while 48 percent of the multiple embryo transfers resulted in multiple births.


SET is becoming the new normal in Europe, with many countries focusing on SET.  The percentage of SET in early adapting countries include:

  • Sweden – 69 percent 

  • Finland – 50 percent

  • Belgium – 48 percent

  • Slovenia – 30 percent

While the United States currently has multiple embryo transfer rates over 90 percent, those figures are beginning to change. In 2007, 7.2 percent of transfers used SET.  This was up from 5.2 percent in 2008 and 0.7 percent in 2003.

SET at New Hope Fertility Center

At New Hope Fertility Center, we have been champions of SET for years.   When used in conjunction with our Natural IVF and Mini IVF procedures, we are able to work with your body’s natural cycle.  We focus on fully understanding the needs of your body and prescribe a regimen that enhances your body’s naturally occurring fertility.  We believe that SET allows for the best outcomes for both mother and child without decreasing success rates.

Frozen Embryo Transfer Success Stories

Posted by NHFC

Baby and Mother (2).jpgBased on recent studies, the chance for a successful pregnancy through Frozen Embryo Transfer (FET) is comparable to fresh IVF cycle transfers. FET success has improved dramatically over the last several years. FETs are typically a Single Embryo Transfer after a woman’s body is prepared for pregnancy. Good eggs create quality embryos. Multiple embryo transfers do not increase a woman’s chances of conception – only the likelihood of a multiple pregnancy. These high quality embryos can be transferred one at a time to the mother at the time of a fresh IVF cycle – or – through future FET procedures. Single Embryo Transfers through FET also help couples build balanced families through gender selection.

New IVF Strategies Aren't So New After All

Posted by NHFC

As seen in this morning's Wall Street Journal article titled "New Strategy May Help Success of In Vitro Fertilization," recent studies within the fertility care field are linking frozen embryo transfers with an increase in healthy pregnancies following IVF treatment.

The "3 separate randomized and controlled studies involving 633 women with an average age of 35" fairly represent the group of couples we've helped get pregnant with frozen embryo transfers: New Hope's latest SART statistics show 44% of our patients age 35 and under achieved a healthy pregnancy following frozen embryo transfers, and 64% of our patients got pregnant using frozen donor embryos.

Frozen embryo transfers (FET) have indeed produced high rates of success at our clinic, and we continue to encourage the practice when counseling our patients.  Not only do FETs increase chances of healthy pregnancy and live births, but the process with which we freeze them also contributes to the health of embryos.  Vitrification, a flash-freezing method we've utilized since our center opened in 2004, has a 98% thaw survival rate here at New Hope, giving our patients peace of mind with every frozen embryo transferred.

The practice of frozen embryo transfers also encourages the practice of single embryo transfers. Because frozen embryos increase the chance of pregnancy, FETs subsequently decrease the need to transfer more than 1 embryo at a time.  Single embryo transfers, along with our minimal stimulation protocols like Mini-IVF™ and Natural Cycle IVF, significantly decrease risks associated with multiple births.  At the hands of our experienced team of fertility specialists, we've been able to prove time and again that with these methods combined, IVF can be safe and more cost-effective for patients wishing to get pregnant without overstimulation.

Infertility in Your 30s | IVF Success Stories

Posted by NHFC

Suffering from secondary infertility (having trouble conceiving with a second child) or experiencing trouble conceiving after entering your 30s?  You're not alone.  At New Hope Fertility, we meet many women who face this harsh reality, even if they had no trouble conceiving with their first child.

For many women, trouble getting pregnant in their 30s is due to diminished ovarian reserve, which can be caused by high FSH levels or reproductive disorders like PCOS.  High FSH levels are associated with a decrease in ovarian function and get higher as a woman ages, which can occur more abruptly with some women in their 30s compared to their fertile counterparts of the same age.  Health issues like PCOS can result in follicles being underdeveloped or, in worst case scenarios, completely absent because of the presence of cysts.  And finally tubal issues, often resulting from scar tissue related to childbirth or pelvic inflammatory disease, are very common for women in their 30s, which can also inhibit the ability to conceive and sometimes cause miscarriages.

Our doctors recently helped a few of patients in their 30s get pregnant with our minimal stimulation IVF protocols.

Our first patient was a 36-year-old who had trouble getting pregnant with her second child.  Because Ms. 36 was young and otherwise healthy, we chose to treat her with our Mini-IVF™ treatment, which uses less hormone drugs than conventional IVF protocols. After her single embryo transfer, which we utilize to mimic the body's naturally occurring processes, we're happy to announce that Ms. 36 got pregnant. Congratulations, Ms. 36!

Our second success story involved a 31-year-old who came to New Hope with a history of secondary infertility.   With the embryos she had frozen at another clinic, we tried two frozen embryo transfers, which unfortunately did not take.  On Ms. 31's third frozen embryo transfer, however, she got pregnant. Congrats Ms. 31!

Our third IVF success story helped a 38-year-old with a history of miscarriage.  Like Ms. 36, she completed 1 Mini-IVF cycle. After freezing her embryos she had an unsuccessful frozen embryo transfer, but a month later she had another and got pregnant.  Congrats Ms. 38!

For more success stories like these, head over to our Success Stories section on our blog and or our website.  Congrats to Ms. 36, Ms. 31 & Ms. 38!
